description

Hciattach is
used to attach a serial UART to the Bluetooth stack as HCI
transport interface.

options

-b

Send break.

-n

Don’t detach from controlling terminal.

-p

Print the PID when detaching.

-ttimeout

Specify an initialization
timeout. (Default is 5 seconds.)

-sspeed

Specify an initial speed
instead of the hardware default.

-l

List all available configurations.

-r

Set the HCI device into raw mode (the kernel and
bluetoothd will ignore it).

tty

This specifies the serial device to attach. A leading
/dev can be omitted. Examples: /dev/ttyS1
ttyS2

type|id

The type or id of
the Bluetooth device that is to be attached, i.e. vendor or
other device specific identifier. Currently supported types
are

speed

The speed specifies the UART speed to use.
Baudrates higher than 115.200bps require vendor specific
initializations that are not implemented for all types of
devices. In general the following speeds are supported:

9600, 19200,
38400, 57600, 115200, 230400, 460800, 921600

Supported
vendor devices are automatically initialised to their
respective best settings.

flow

If the keyword flow is
appended to the list of options then hardware flow control
is forced on the serial link ( CRTSCTS ). All above
mentioned device types have flow set by default. To
force no flow control use noflow instead.

sleep

Enables hardware specific power management feature. If
sleep is appended to the list of options then this
feature is enabled. To disable this feature use
nosleep instead. All above mentioned device types
have nosleep set by default.

Note: This
option will only be valid for hardware which support
hardware specific power management enable option from
host.

bdaddr

The bdaddr specifies the
Bluetooth Address to use. Some devices (like the STLC2500)
do not store the Bluetooth address in hardware memory.
Instead it must be uploaded during the initialization
process. If this argument is specified, then the address
will be used to initialize the device. Otherwise, a default
address will be used.
